It doesnt even have a skybox cause its just a REALLY tall box that everyone places in that teleports to smaller rooms. But when your at the top of that box and your looking down thru the glass you have to break, it gets REAL laggy. None of my brushwork is colliding with each other, I did the nodraw stuff, even on faces you cant see but had textures, I dont think I really did anything with details yet because there really is not much with details in the map :- Still learning that part.
